ABSTRACT:
A cold-cathode fluorescent discharge tube has a pair of electrodes for performing discharge between the electrodes in response to the application of a voltage therebetween. The fluorescent discharge tube of the invention includes an auxiliary electrode provided in the vicinity of one of the pair of electrodes, and a unit for applying the voltage between the pair of electrodes and between the auxiliary electrode and the one of the electrodes. With the auxiliary electrode, a discharge is firstly started between the auxiliary electrode and the one of the electrodes in response to the application of the voltage between the pair of electrodes. Thereafter, a discharge is started between the pair of electrodes. Thus, the start discharge is generated in the discharge tube in a relatively short period of time even if the discharge tube is set in the off state for a long time, particularly in the dark at a low temperature.
